Made to Measure

The strap for this watch is made to measure

On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the best strap for this Omega model?

The best strap depends on use and personal taste. For formal elegance, we recommend black or dark brown alligator; for versatility and warmth, vegetable-tanned calf leather; for practicality, burgundy brown shell cordovan. The ideal choice enhances the warm tone of the yellow gold without competing visually with the case.

How do you change the strap on the Constellation 131.53.29.20.55.001?

The strap is changed by removing the spring bars from the lugs using a specialized tool or a sterile needle. Insert the spring bar into the new strap, thread it through the lugs, and return the spring to its resting position. If you are not experienced, we recommend entrusting the operation to a watchmaker to avoid damaging the case.

How long does a leather strap last on a watch like this?

The lifespan depends on frequency of use, climate, and leather quality. A high-quality alligator or shell cordovan strap resists an average of 4-6 years with daily use, developing a patina that makes it more distinctive over time. Vegetable-tanned leathers naturally darken; this is normal and desirable. A construction warranty (such as Casati Milano's: 18 months) protects the customer from manufacturing defects.

The next step

The right strap isn’t chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
